Good feedback. I am watching my Aquamaxx reactor carefully for cracks. Pax Bellum stuff is sexy as heck but I was in your same boat, no space. If they make a short, squatty one, I'm in!!! As for the Deltec v. Nyos, my Deltec is only slightly higher noise than the Varios. If the Nyos is even quieter, what a score!!! Couldn't go wrong with either choice.Your build thread helped me go with Blue Tide & Reef Octopus Varios, so thank you!
Yeah, I'm still tinkering with it. I'm genuinely worried about heat. There are lots of threads about people starting a macro-algae reactor, but few who have run them for months or a year. There are a few posts of them cracking and leaking after a long time.
I think ReefBum and others are pushing the heat angle to sell Pax Bellum, but it is a concern. I'm not going to wrap it in vinyl yet and I'll monitor the heat. I asked one of the reactor manufacturers and they guessed it would work for a few years before cracking. It depends on the lights and other factors. If I had space, I would have done the Pax Bellum just because it's a known quanity.
Love the NYOS, the first once I received was broken and poorly built which is hard to explain. The replacement unit is perfect. Another thread on R2R said the NYOS was quieter than the Deltec, that heavily influenced me.
